Open- OP-470: 1000V/mV Min iggp gain of the OP-270 (OP-470) is over 1.5 million (1.0 = Outstanding CMRR OP-270: 106dB Min iniltion) into a 10kQ load ensuring excellent gain accuracy OP-470: 110dB Min and linearity, even in high-gain applications. Input bias m Slew Rate 3.0V/us TYP currents under+20nA (+25nA) which reduces errors due = Gain Bandwidth Product 6MHZ Typ to signal source resistance. The OP-270's (OP-470's) = Industry Standard Pinouts CMRR of over 106dB (110dB) and PSRR of less than 3.2UVNV (1.8nV/V) significantly reduce errors due to ground APPLICATIONS noise and power supply fluctuations. Power consumption of the dual OP-270 (quad OP-470) is one-third less than two (four) OP-27s, a significant advantage for power conscious applications. The OP-270 and OP-470 are unity- ; ve: gain stable with a gain bandwidth product of 6MHz anda Strain Gauge Amplifiers : slew rate of 3.0V/us. = Accelerometer Amplifiers oo Infrared Detectors For applications requiring higher performance, see the LT1124 and LT1125 data sheets. = Two and Three Op Amp Instrumentation Amplifiers = Low Noise Signal Processing m Microvolt Accuracy Threshold Detection Strain Gauge Signal Conditioner with Bridge Excitation 0.1Hz to 10Hz Voltage Noise +15V 23602 J ow LT1019-5 REFERENCE OUT Rca VOLTAGE NOISE (40nV/DIV) 3502 BRIDGE OV TG 10V OUTPUT 301k" TIME (s) OP-270/470 TAOZ GAIN TRIM OP270'470 + TAQtOP-270/OP-470 ABSOLUTE MAXIMUM RATINGS Operating Temperature Range Supply Voltage .......ssscsssssscsssssssscssesessesesseseecteeee +18V OPZ7OA/OPATOA ......coeeeeseesteerereretien 55C to 125C Differential Input Voltage (Note 4) ..............ssesses- +1.0V OP270E/0P470E 40C 10 85C Differential Input Current (Note 4)... +25mA OP270G/OPA70G ......-ssesecsrcessssnnssneseenes 0 Input Voltages ......cccsssesssseesen Equal to Supply Voltages Stor no Temper ature Range 65C 10 150C Output Short Circuit Duration ....... ee Indefinite FADES oo. eeseeseessen stesneenenesoneenann P Lead Temperature (Soldering, 10 sec.) 0... 300C PACKAGE/ORDER INFORMATION ToP view TOP VIEW TOP VIEW outa (7) T ia] ourp ora 7a] outro ota fav" INA Eh] Rie IND AINA eH lg 15] IND -Na [2] 7] ours wna (Bl 12} ND wa BFS Tq] sino Pa sINA a re] -iNe v Ly" ve FY: 3] v- vG <i BELL +n [8] > 10} +INC ne BE > 2] sinc PACKAGE me a] -e ve BR i] -c 10 OUT B LZ [a] ourc outs ZF 8-LEAD CERAMIC DIP i] out B-LEAD PLASTIC DIP J PACKAGE ne [Ey [s] Ne IP eur. rows 14-LEAD CERAMIC DIP 5S PAGKAGE N PACKAGE 14-LEAD PLASTIC DIP T6-LEAD PLASTIC SOL OP270/470 + POIOZ OP 270/470 POW ORDER PART ORDER PART ORDER PART NUMBER NUMBER NUMBER OP-270AJ8 OP-470Ad OP-270EJ8 OP-470EJ OP-470GS OP-270GN8 OP-470GN ELECTRICAL CHARACTERISTICS Vg = +15V, T, = 25C, unless otherwise noted. oP-270G OP-270A/E OP-470A/E OP-470G SYMBOL | PARAMETER CONDITIONS MIN TYP MAX | MIN TYP MAX MIN TYP MAX | UNITS Vos input Offset Voltage OP-270 10 75 50 250 wv OP-470 100 400 400 1000 uv los Input Offset Current OP-270 Vey = OV 5 15 6 20 nA OP-470 Voy = OV 6 20 12 = 30 nA \p Input Bias Current Vom = OV +7 +20 +7 +25 +15 +60 nA n P-P Input Noise Voltage 0.1Hz to 10Hz (Note 1) 80 200 80 =. 200 80 200 | nVp-p ey Input Noise Voltage Density | fg = 10Hz (Note 2) 3.6 6.5 3.6 6.5 3.6 866.5 nV/NHz fo = 100Hz (Note 2) 3.2 5.5 3.2 5.5 3.2 5.5 | nVVHz fo = 1000Hz (Note 2) 3.2 5.0 3.2 5.0 3.2 5.0 | nV/VHz LS Wee 2-121OP-270/OP-470 ELECTRICAL CHARACTERISTICS v, - +15v, 1, = 25C, unless otherwise noted.
